ISL6334A規(guī)格書詳情

The ISL6334, ISL6334A control microprocessor core voltage

regulation by driving up to 4 interleaved synchronous-rectified

buck channels in parallel. This multiphase architecture results

in multiplying channel ripple frequency and reducing input and

output ripple currents. Lower ripple results in fewer

components, lower cost, reduced power dissipation, and

smaller implementation area.

Microprocessor loads can generate load transients with

extremely fast edge rates and requires high efficiency at light

load. The ISL6334, ISL6334A utilizes Intersil’s proprietary

Active Pulse Positioning (APP), Adaptive Phase Alignment

(APA) modulation scheme, active phase adding and

dropping to achieve and maintain the extremely fast

transient response with fewer output capacitors and high

efficiency from light to full load.

The ISL6334, ISL6334A is designed to be completely

compliant with Intel VR11.1 specifications. It accurately

reports the load current via IMON pin to the microprocessor,

which sends an active low PSI# signal to the controller at low

power mode. The controller then enters 1- or 2-phase

operation with diode emulation option to reduce magnetic

core and switching losses, yielding high efficiency at light

load. After the PSI# signal is de-asserted, the dropped

phase(s) are added back to sustain heavy load transient

response and efficiency.

Today’s microprocessors require a tightly regulated output

voltage position versus load current (droop). The ISL6334,

ISL6334A senses the output current continuously by utilizing

patented techniques to measure the voltage across the

dedicated current sense resistor or the DCR of the output

inductor. The sensed current flows out of FB pin to develop the

precision voltage drop across the feedback resistor for droop

control. Current sensing circuits also provide the needed

signals for channel-current balancing, average overcurrent

protection and individual phase current limiting. An NTC

thermistor’s temperature is sensed via TM pin and internally

digitized for thermal monitoring and for integrated thermal

compensation of the current sense elements.

A unity gain, differential amplifier is provided for remote voltage

sensing and completely eliminates any potential difference

between remote and local grounds. This improves regulation

and protection accuracy. The threshold-sensitive enable input is

available to accurately coordinate the start-up of the ISL6334,

ISL6334A with any other voltage rail. Dynamic-VID?

technology allows seamless on-the-fly VID changes. The

offset pin allows accurate voltage offset settings that are

independent of VID setting.
